连续关闭 2 个 ViewController [英] Dismissing 2 ViewController consecutively

问题描述

我尝试了 2 种方法连续关闭 2 个视图控制器，但只有其中一个被关闭，而不是第二个

I try 2 ways to dismissed 2 viewcontrollers consecutively but only one of them got dismissed not the second one

方法 1

-(void) LoginDone:(NSNotification *)notif 
 {
 [self dismissViewControllerAnimated:YES completion:NULL];   //previous viewcontroller
 [self dismissViewControllerAnimated:YES completion:NULL];   //current viewcontroller
  }

方法2

-(void) LoginDone:(NSNotification *)notif 
{
[self dismissViewControllerAnimated:YES completion:NULL];
 [[NSNotificationCenter defaultCenter] postNotificationName:@"LoginDone2" object:nil];

 }

-(void) LoginDone2:(NSNotification *)notif 
{
     [self dismissViewControllerAnimated:YES completion:NULL];


 }

我需要找到一种方法来连续关闭前一个视图控制器和当前视图控制器.

I need to find out a way to dismiss both the previous viewcontroller and current viewcontroller consecutively.

推荐答案

这是一个老问题，但它似乎正是我目前遇到的问题.这是我所做的:

This is now an old question, but it seems to be exactly the problem I am having presently. Here what I did:

    [self.presentingViewController.presentingViewController
     dismissViewControllerAnimated:YES completion:nil];

它对我有用.我希望它对某人有用.

And it works for me. I hope it can be useful to someone.
